常用参数
1 –concurrency #代表并发数量,多个可以用逗号隔开。例如:–concurrency=50,200,500 2 –engines #代表要测试的引擎,可以有多个,用分隔符隔开。例如:–engines=myisam,innodb,memory 3 –iterations #代表要在不同并发环境下,各自运行测试多少次。 4 –auto-generate-sql #代表用mysqlslap工具自己生成的SQL脚本来测试并发压力。 5 –auto-generate-sql-add-auto-increment #代表对生成的表自动添加auto_increment列,从5.1.18版本开始, 6 –auto-generate-sql-load-type #代表要测试的环境是读操作还是写操作还是两者混合的(read,write,update,mixed) 7 –number-of-queries #代表总共要运行多少条查询。 8 –debug-info #代表要额外输出CPU以及内存的相关信息。 9 –number-int-cols #代表示例表中的INTEGER类型的属性有几个。 10 –number-char-cols #代表示例表中的vachar类型的属性有几个。 11 –create-schema #代表自定义的测试库名称。 12 –query #代表自定义的测试SQL脚本。
